IMPROVEMENT IN LlFTlNG-JACKS.

Specification forming part of Letters Patent No. 147,440, dated February10, 1874; application filed December 3l, 1873.

To all lwhom 'it may concern:

1 Beit known that I, (JOE D. SMITH, of Smithtown, Suffolk county, Stateof New York, have invented certain Improvements in Wagon- Jacks, ofwhich the following is a specifica- Jfion:

The object of niy invention is to provide for a cheap, light, strong,self-adjustable, and reversible wagon-jack.

The present-used jacks for lifting up and supporting wagons While thewheels are removed for oiling or repairing are, as a rule, too costlyfor general adoption, especially for fariners, and too heavy andcumbersome to carry along in the wagon. \'Vith a view to overcome thesedifeulties, I have invented the hereindescribed wagon-j ack.

In order to more fully describe in y invention, I refer to theaccompanying drawing' forming a part of this specification.

Figure I is a top view of myiniproved wagonjack when folded together.Fig. II is a side view of the saine in .position when placed under awagon.

A and B are two legs, inade 'ot' strong, serviceable wood, with theinserted metal strips or tips c and b placed thereon for the purpose ofpreventing slipping on hard ground.A Between the opposite ends of theselegs A and B is pivoted, at c, between the washers s s, the lever C,with its longest arm, d, extending t0- ward the operator, the other andshorter arm, c, having notches f and g on either side for preventingslipping from the axle or any part of the wagon under which it isplaced. At the end of the arm c are fastened two Washers, h and c',having a hole, 7a, in which is inserted and riveted loosely Von the backthe metal catch D. In both sides of the leg B, a short distance from thetop, (about the length of the catch D,) is inserted a metallic bar orpin, E, which goes through this leg and extends one inch or so 011 bothsides.

The operation of my improved wagonjaek is simply this: The legs 'A and Bare spread out so far that the lever C Will readily pass under the partof the wagon which is to be elevated. It makes no difference how thejack is unfolded, as it Will `operate equally well on either side,being, in this respect, reversible. The arm c is placed under the axleor any other part of the Wagon and the arni cl depressed, which elevatesthe wagon, and the catch D is placed against the bar or pin E to hold itin this elevated position.

Having thus described my invention, I de sire to claim- A wagon-jackconsisting of the two' legs A and B, lever O, catch D, and box or pin E,substantially as and for the purpose hereinbefore set forth.

This specification signed this day, the 17th day of December, 1872.

COE D. SMITH.
